When your Geni Garage Door Opener Only One Light Working, it can be confusing and inconvenient—especially when your garage feels darker than usual. Many homeowners experience this issue and worry it means a major repair. The good news is that, in most cases, this problem is easy to diagnose and fix with the right guidance.
Why Is My Geni Garage Door Opener Only One Light Working?
This is one of the most common “People Also Ask” questions related to Genie openers.
In most Genie garage door opener models, two light sockets are designed to work together. When only one light turns on, the issue usually falls into one of these categories:
- Burned-out bulb
- Incompatible bulb type
- Faulty light socket
- Wiring or circuit board issue
According to residential garage equipment technicians, over 60% of lighting issues are caused by bulb incompatibility, not electrical failure.
How Garage Door Opener Lights Are Designed to Work
Understanding the system helps prevent misdiagnosis.
Basic Lighting Function
- Lights activate when the door opens or closes
- They turn off automatically after 3–5 minutes
- Both sockets receive power simultaneously
If one light fails, the opener will still operate normally—making the issue easy to overlook.
Common Causes of One Light Not Working
1. Burned-Out or Loose Light Bulb
This is the simplest and most frequent cause.
What to Check
- Bulb filament damage
